Abstract
A fluid power assistance control device includes a rotatable input, a first valve coupled to the input and a second valve. The second valve is rotatable relative to the first valve and a projection between the first and second valves limits the rotation therebetween. The projection cooperates with the valve to substantially define fluid paths which communicate with an outlet and also defines flow restrictions within the paths such that rotation between the valves increases flow restriction in one of the fluid paths and decreases flow restriction in another of the fluid paths. The valves cooperate to define reaction cavities which communicate with respective fluid paths so that fluid communicated to one of the reaction cavities opposes the rotation of the input.
